I can't see that this code gets anything more than Get-Service - since Get-Service is an interface to System.ServiceProcess.ServiceController
Some of the info can be derived from the registry or running SC.EXE - registry interpretation requires information about enumerations for various keys, SC would require parsing output. Neither gives you information about the running process if there is one which also used by the client.
Looks like no way of getting away from the overhead of WMI - digging around for extra information or messing around with unstructured text will get you so far, but not all the info sought.

Scott and David, I’m not finding any .net call that will produce the “StartupType” for a service that is already installed. There is a documented way to do it from a Win32 API; but, that involves using P/Invoke. See here: http://www.leeholmes.com/blog/2009/01/19/powershell-pinvoke-walkthrough/ and here: http://pinvoke.net/default.aspx/advapi32/QueryServiceConfig.html

This is what I have so far:
function XymonSvcsNET2
{
$result =$Services =$COLUMNNAME="Name" $COLUMNSTATUS="Status" $COLUMNDESCRIPTION="Description" #[Reflection.Assembly]::Load(‘System.ServiceProcess,Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a’)
#get all the services installed on the local machine $serviceController ="[svcs]""--------------------------------------------------------------------------------------------------------------"
"{0,-50} {1,-20} {2,-20}" -f ` $COLUMNNAME, $COLUMNSTATUS, $COLUMNDESCRIPTION"--------------------------------------------------------------------------------------------------------------"
foreach ($svc in $serviceController) { "{0,-50} {1,-20} {2,-20}" -f ` $svc.Name, $svc.Status, $svc.DisplayName }}
I did get the formatting figured out finally after about 6 hours. The only piece that I cannot figure out is the service startup type, if I can get some help on that I think this is workable.
I'm a complete newbie at powershell, so comments/help appreciated.

David, you can also use the “Load” method instead as follows:
Reflection.Assembly::Load(‘System.ServiceProcess, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a’)

Ray,
Thanks for the code. I’m a bit wary of using something with such a version specific path though – is that seriously a “standard” interface to a .Net DLL that can be expected to have some degree of persistence?
I’m offsite this week, will try to take a look next week.
Thanks, David.

Thank you Raymond… If I knew how to implement it I would. Hopefully David or Henrik can find the time to experiment with it.
I'm seeing all kinds of problems with the PS client…. If this keeps up I'll have to remove it. It pegged one of my servers at 100% for over an hour, stuck on the WMI yesterday.

Opps… I missed the “.” in the Reflection.Assembly. Also, you can pipe it to out-null to avoid any unwanted output. So:
| out-null

Scot and David, if you’d prefer to implement a .net pure call for services you can try the following:
your path to the file may very
#get all the services installed on the local machine
$serviceController = System.ServiceProcess.ServiceController::GetServices()
foreach ($svc in $serviceController) {
# should indicate: Stopped, Running, or Paused … others??? write-host $svc.Status # the service name write-host $svc.Name # the service display name write-host $svc.DisplayName}
